4.1 Introduction Computers are all around us: in cars, kitchen scales, digital cameras, etc. But how do they store the data they hold? This unit will help you to understand how the data in a computer represents something in the outside world. You will also explore how ASCII code and Unicode are used to control data.Author(s): The Open University

8.1 Introduction Models are mechanisms for communication. This unit looks at what a model is and what the process of modelling is about. The techniques discussed here are applicable to a wide range of systems and have one thing in common: they are all commonly used diagramming techniques. The five techniques are: data flow diagrams, use case modelling, activity diagrams, entity–relationship diagrams and state machines.Author(s): The Open University

1.1 Introduction No idea how relational database systems are constructed? Did you know that they underpin the majority of the managed data storage in computer systems? This unit has been designed to give you an overview of the developmental lifecycle for a database system, explaining the importance of data analysis and highlighting how database development differs from traditional software development.Author(s): The Open University

Modern techniques for revealing where and when different parts of the brain become active have recently provided a window on the processes of attention. For example, one of these brain-scanning techniques, functional magnetic resonance imaging (fMRI), has been used to show the behaviour of an area of the brain that responds to speech. It turns out also to become activated in a person viewing lips making speech movements in the absence of sound. For this to happen there must be connecti

The above account of having attention taken away from the intended target reminds us that, while it may be advantageous from a survival point of view to have attention captured by novel events, these events are actually distractions from the current object of attention. Those who have to work in open-plan offices, or try to study while others watch TV, will know how distracting extraneous material can be. Some try to escape by wearing headphones, hoping that music will be less distracting, bu

The binding of features emerges as being a very significant process when displays are brief, because there is so little time in which to unite them. With normal viewing, such as when you examine the letters and words on this page, it is not obvious to introspection that binding is taking place. However, if, as explained above, it is a necessary precursor to conscious awareness, the process must also occur when we examine long-lived visual displays. Researchers have attempted to demonstrate th

I introduced Section 1 by suggesting that the auditory system had a special problem: unlike the visual system, it needed processes which would permit a listener to attend to a specific set of sounds without being confused by the overlap of other, irrelevant noises. The implication of that line of argument was that vision had no need of any such system. However, although we do not see simultaneously everything that surrounds us, we can certainly see more than one thing at a time. Earlie

To cover some of the concept of attention (we have only a unit, and there are whole books on the subject) I shall follow an approximately historical sequence, showing how generations of psychologists have tackled the issues and gradually refined and developed their theories. You will discover that initially there seemed to them to be only one role for attention, but that gradually it has been implicated in an ever-widening range of mental processes. As we work through the subject, two basic i

This section explores how scientific knowledge and scientific literacy can be built up through working in communities of practice (groups of people who work together and share a common language). We also look at issues relating to the ideas of subjectivity and objectivity, and at deductive and inductive thinking. Finally, we explore the public understanding of science by examining how society, in wider terms, constructs or influences scientific thinking and understanding.

A rapidly growing branch of medical science has begun to try to measure the physiological impact of grief. Incorporated into this study are the ways in which bodily functions change in response to emotional stimuli. This new area of scientific research has been called ‘psychoneuroimmunology’ and is the study of how different feelings and stresses lead to changes in hormone levels and other metabolic functions within the body. These can often be quantified through blood tests and othe
